How a .si name is registered, how it ends, and how much of the space is already taken. Every figure carries one of three labels, the date it was read and, where we measured it ourselves, the method. Nothing here is advice on what to register. Nothing here is legal advice.
If your name is on the radar
A name appears on the drop radar when the registry’s record for it carries a quarantine status: the registration ran out, or the name was returned or deleted, and the registry has scheduled it for deletion.
If it is your name, ask the registrar you registered it with to renew or restore it before the latest release date shown beside it; the registry’s terms allow a renewal until quarantine ends.
Do not wait for the last day: the registry does not publish the hour, and once the name is deleted anybody can register it.
Registry rule Register.si, General terms (cl. 5.3.2, 5.4.2 and 5.4.3); Register.si, Renewing and deleting read 6 Oct 2026
The drop radar shows that date for every name it follows. How it works says how each state is decided.
The life of a .si name
- Day 0RegisteredFor 1 to 5 years. In the first 16 days it can be returned, but only while it has no name servers.
- Expiry dateQuarantineNo grace period. Up to 30 days, and the holder can still renew.
- + 30 days at mostDeletedCan be registered again at once. The hour is not published.
- Registration
- Anybody can register a .si name: a natural or a legal person, with no residency test. A name is 2 to 63 characters long and is registered for 1 to 5 years.
- Registry rule Register.si, General terms (cl. 2.7, 4.1, 4.2 and 5.1.1); Register.si, Registration and return read 6 Oct 2026
- Return right
- For 16 days the holder can give the name back, but only while it has no name servers. A returned name is not gone at once: in the registry’s records it carries a quarantine status, like a name a registrar deleted.
- Registry rule On the registry’s site, no single page is linked here; the remark on returned names is our measurement read 6 Oct 2026
- Expiry
- There is no grace period. A name that is not renewed goes into quarantine on its expiry date.
- Registry rule Register.si, General terms (cl. 5.3.2); Register.si, Renewing and deleting read 6 Oct 2026
- Quarantine
- Quarantine lasts 30 days at most. The name is still registered to its holder, who can renew it until quarantine ends. In our probes a name in quarantine had no name servers at the registry, so it does not resolve.
- Registry rule Register.si, General terms (cl. 5.4.2 and 5.4.3; the name-server remark is our measurement); Register.si, Domain statuses read 6 Oct 2026
- Deletion
- When quarantine ends the name is deleted and can be registered again at once. The registry does not publish the hour. On 6 Oct 2026 a name whose latest release date was that day was still in quarantine at 07:57 UTC and had been deleted and registered again by 14:17 UTC. That is one name on one day, not a rule.
- Our measurement Register.si, General terms (the deletion itself is a registry rule, cl. 5.4.3) measured 6 Oct 2026 Method: The registry’s pages were read for a release hour and none was found; one name on its latest release date was asked at the registry’s RDAP service at 07:57 UTC and again at 14:17 UTC.
The latest release date this site shows is the expiry date plus 30 days for an expired name, and the date of the last change plus 30 days for a name that was returned or deleted. It is the latest date, not an appointment: the holder can end the wait any day by renewing.
Our measurement Register.si, RDAP measured 6 Oct 2026 Method: Computed from the dates in the registry’s RDAP record of each name.
.si is not .com
Most explanations of expiry in English describe .com. These are the points where .si works differently.
- No grace period
- The day after the expiry date is not a grace day. The name is already in quarantine, and the 30 days are running.
- Registry rule Register.si, General terms (cl. 5.3.2); Register.si, Renewing and deleting read 6 Oct 2026
- No WHOIS privacy
- There is no privacy service. The contact data of a legal entity is published in full; for a natural person only the e-mail address is shown.
- Registry rule Register.si, Data policy (what is published; that no privacy service is sold is a registrar’s statement) read 6 Oct 2026
- One fee, no premium names
- We found no premium tier on the registry’s pages: a common word and a random string cost the same. The registry fee is reported as EUR 10 per registration; we did not read that figure on the registry’s own price list.
- Reported by others CircleID, 1 Oct 2026 (the fee; the absence of a premium tier is our reading of the registry’s pages) read 6 Oct 2026
- Anybody may register
- The terms ask for no residency: the holder is a natural or a legal person. Some pages elsewhere still say a link to Slovenia is required; the registry’s terms do not.
- Registry rule Register.si, General terms (cl. 2.7); Register.si, Registration and return read 6 Oct 2026
- Almost nothing is reserved
- The reserved list holds a handful of names. We found no block list of generic words.
- Registry rule Register.si, Reserved names read 6 Oct 2026
- Registrant data is checked
- The registry’s policy says registrant data is verified at registration, renewal and transfer. A failed check opens 21 days to correct the data; after that the name can be deactivated or deleted. We read this; we did not test it.
- Registry rule Register.si, Data policy read 6 Oct 2026
- Its own dispute procedure
- The registry runs its own dispute procedure (ADR). A complaint needs a right that is valid in Slovenia, and the complainant pays: EUR 700 including VAT for 1 to 5 names with one arbiter. For a .com name the procedure is the UDRP, for which WIPO lists USD 1,500 for 1 to 5 names with one panelist. This page says nothing about who would win.

Measured: how full it is
How much of the English dictionary already has name servers on .si. A name with name servers is registered; a name without them may be registered too, so these figures are a floor.
Share with name servers on .si, of 17,760 words from a frequency list of 20,000 English words. One mark is two points.
- The 6,267 most common words97%
- The middle band89%
- The least common band81%
- All 17,760 words89%
Our measurement measured 6 Oct 2026 Method: One NS question per name to the registry’s own name servers, without recursion.
The trap: no name servers does not mean not registered. Of 831 names without name servers that we then asked at the registry, 137 were registered: about 1 in 6. Among common dictionary words it was 83 of 133. A name in quarantine has no name servers either. A DNS check finds candidates; only the registry’s answer decides, and even that is not a registrar’s yes.
Our measurement Register.si, RDAP measured 6 Oct 2026 Method: Each name without name servers was then asked at the registry’s RDAP service; a “not found” was asked twice.
For scale: 46,066 new .si names were registered in September 2026, according to press reports. That is a press figure, not a statement of the registry.

The three-letter space
There are 17,576 three-letter combinations, from aaa to zzz. We asked about every one of them.
- 15,494 have name servers
- 452 registered, no name servers
- 1,630 not found at the registry
15,946 of the 17,576 (91%) were registered on that day. Of the 1,630 not found, 1,193 have no vowel and no y, 408 have a y and no vowel, and 29 contain a vowel. Not one is made only of the common consonants b c d f g h k l m n p r s t: every one carries at least one of j q v w x y z.

Sales with a source
Every sale on this list is a single dictionary word. It is too few to price anything, and this page does not try. No average, no estimate. Prices are as the source reported them; a dash means the source does not say who bought. “Verified” means we read the sale at the linked source; “reported” means one source says so and nobody else confirms it.
